Has anyone done bumper cover repairs?
Will polyurethane adhesives stick to it?

Your best bet is your favorite body shop for the repair to be done right.

It isn't damaged like that, I am trying to fix the dimples on the sides of the rear bumper cover that I see a majority of our cars have.
I found a product called Duramix online but thought I would ask around here before I dropped $100 on the gun and the goop

Duramix isn't a filler, it is more of an adhesive, and a damn good adhesive at that.

Which bumper dimples are you trying to fix? A picture may be in order to make a better assessment.

My intent is to bond a flexible reinforcement to the inside.
I have 3M 5200 polyurethane adhesive sealant but I don't want to find out it will damage my cover.

That fast cure adhesieve should work, I would try a dab on the back of the bumper first, just to make sure.

I put a dab of 5200 on it in a safe trial area this afternoon.
I'll search out the correct adhesive tomorrow if I don't like what I see.

Gary,

5200 is gross overkill.....IF you ever should want to remove it!!:shake:

Push some styrofoam behind it until you get the desired results and shoot some RTV silicone in there to hold it in place!!:beer:

It works like a contact adhesive, apply to both sides, wait 5 minutes, and stick it. Bonds like CRAZY. I've used it to stick trim back onto many many cars. Clean both surfaces with alcohol first, and as a bonus it's only 5 bucks at Advance/Autozone.

I always have 5200 on hand but you're right it is serious business.
My plan is a strip of fiberglass (cut off from a boat mold) strategically placed behind the sag, stiff but still flexible.
I picked up some 3M plastic/rubber bonding adhesive from NAPA this morning.
I plan on doing the fix this afternoon.
I considered the styrofoam angle too but saw it as a water trap.
